Spotted Lanternfly turns up in the valley this month
July 28, 2026
have appeared in the valley this month, with at least one research-grade sighting confirmed at the Columbia River Greenway in July. This is the quiet beginning of what tends to become a harder-to-control outbreak: first a few scattered records, then they are everywhere. The insect feeds by piercing bark and drawing sap from dozens of host plants — grapes, hops, apples, black walnut — but it shows a strong preference for Tree-of-Heaven, the invasive Asian tree that has spread along the valley's roadsides and riverbanks and now serves as the species' primary staging habitat.
The timing is notable. Hampden County has been under moderate drought (D1) for at least three consecutive weeks, stressing the same trees the lanternflies are already targeting — and trees under prolonged water stress tend to have fewer resources to cope with additional pressure. Anyone finding egg masses — flat, mud-colored smears on bark, stones, or outdoor furniture — should scrape them off and report them. At this scale, early removal is still the most effective intervention.
and wild bergamot were at their peak when the bees appeared — the kind of phenological alignment that is easy to miss and genuinely hard to replace. Finding these two species foraging on valley-floor meadows and farm edges in mid-July is not a sign of recovery so much as evidence that
the margin is thin and still present
. These bees depend on a continuous thread of flowering plants from spring through fall, and the corridor of wild and semi-wild habitat running the length of this valley is one of the few places in the region where that thread still holds.
